Overlooked, offbeat drama about a flighty woman who spites her husband by dallying with a sensitive, recently divorced surgeon. Classic '60s document and cult favorite offers great performance from the appealing Christie, with Scott fine as the vulnerable surgeon. On-screen performances by the Grateful Dead and Big Brother. Among idiosyncratic director Lester's best. From the novel "Me and the Arch Kook Petulia" by John Haase.
